Hello Mikalai!
Thank you for putting up the study guide:) I had been looking for it for a few days now. Read about it in Jeanne's blog where it came recommended for the exam preparation, but the link on there to the study guide is broken.
The latest one you shared with Mino works well :) except that the links on the Quiz page are still broken:(

could there be another secret link? ;)
Thank you,
